Objectives
The current study aimed at analyzing the associations between latent transitions based on sedentary time and physical activity levels and changes in Health-Related Quality of Life (HRQoL), positive affect, and negative affect over two years in children and adolescents.
Design
Longitudinal design.
Methods
Participants were 1099 children and adolescents (544 girls) ...
Objective
To study physical activity and sleep in Fontan patients and healthy controls before and after an endurance training program, and after 1 year.
Method
Fontan patients (n = 30) and healthy controls (n = 25) wore accelerometers for seven consecutive days and nights during a school week before and after a 12-week endurance training ...
Objective
Nonalcoholic fatty liver disease (NAFLD) is associated with insulin resistance (IR) and visceral adiposity in adults and boys, but girls with NAFLD are understudied. We sought to evaluate adipose, liver, and skeletal muscle insulin sensitivity in obese adolescent females with or without hepatic steatosis (HS) (intrahepatic triglyceride (IHTG) content >5.5%) ...
ABSTRACT
The study analyzed the effect of number of hours and days of accelerometer use on estimates of physical activity (PA) time in adolescents. Cross-sectional study of 784 adolescents from 10 to 14 years old (53.9% girls). Overlapping 95% confidence intervals (95%CI) were used to compare mean light (LPA), moderate (MPA), vigorous (VPA) and moderate ...
Objective
Chronic fatigue syndromemyalgic encephalomyelitis (CFS/ME) is relatively common among children and adolescents; however, little is known about the physical activity levels and patterns of this population. The aim of this study was to examine the underlying patterns of physical activity among youth with mild-to-moderate CFS/ME. Cross-sectional associations ...
Purpose
Emerging data indicate that the timing and rhythms of energetic behaviors may influence metabolism and obesity risk. Our aim was to derive diurnal rest-activity patterns from actigraphy in adolescents and analyze associations with adiposity measures and cardiometabolic risk factors.
Methods
Adolescents in the Project Viva cohort wore a wrist ...
Introduction
Although current guidelines for the early clinical management of sports-related concussion (SRC) call for a gradual return-to-activity, the optimal level of rest needed to promote recovery remains unknown. This paper describes the protocol of the Rest Evaluation for Active Concussion Treatment (ReAct) study which objectively measures physical and cognitive ...
Background
Most Finnish adolescents are not sufficiently physically active. Health education (HE) provides beneficial starting point for physical activity (PA) promotion in schools. This study evaluates an intervention integrated into three HE lessons to increase PA and reduce sedentary behavior (SB) among eighth graders.
Methods
All public secondary schools in ...
Objective
To examine whether the decline in physical activity observed from childhood through adolescence is explained by moderating effects of self-efficacy on concurrent changes in children’s goals and beliefs about their physical activity environments. Method: Latent growth modeling was used in longitudinal tests in a cohort of 79 boys and 108 ...
Purpose
To investigate the association between telecommunication and other screen devices use and subjective and objective sleep measures in adolescents at 17–18 years.
Methods
Cross-sectional study on adolescents aged 17–18 years from a Spanish population-based birth cohort established in Menorca in 1997–1998. Information on devices use was collected using self-reported questionnaires. Mobile Phone ...
